To science we owe it that no man is any longer entitled to consider himself the central point around which the whole Universe of life and motion revolves—the immensely important individual for whose convenience and even luxurious ease and indulgence the whole Universe was made. On one side it has shown us an infinite Universe of stars and suns and worlds at incalculable distances from each other, in whose majestic and awful presence we sink and even our world sinks into insignificance; while, on the other side, the microscope has placed us in communication with new worlds of organized livings beings, gifted with senses, nerves, appetites, and instincts, in every tear and in every drop of putrid water.
Thus science teaches us that we are but an infinitesimal portion of a great whole, that stretches out on every side of us, and above and below us, infinite in its complications, and which infinite wisdom alone can comprehend. Infinite wisdom has arranged the infinite succession of beings, involving the necessity of birth, decay, and death, and made the loftiest virtues possible by providing those conflicts, reverses, trials, and hardships, without which even their names could never have been invented.
Knowledge is convertible into power, and axioms into rules of utility and duty. Modern science is social and communicative. It is moral as well as intellectual; powerful, yet pacific and disinterested; binding man to man as well as to the Universe; filling up the details of obligation, and cherishing impulses of virtue, and, by affording clear proof of the consistency and identity of all interests, substituting co-operation for rivalry, liberality for jealousy, and tending far more powerfully than any other means to realize the spirit of religion, by healing those inveterate disorders which, traced to their real origin, will be found rooted in an ignorant assumption as to the penurious severity of Providence, and the consequent greed of selfish men to confine what seemed as if extorted from it to themselves, or to steal from each other rather than quietly to enjoy their own.
We shall probably never reach those higher forms containing the true differences of things, involving the full discovery and correct expression of their very self or essence. We shall ever fall short of the most general and most simple nature, the ultimate or most comprehensive law. Our widest axioms explain many phenomena, but so too in a degree did the principles or elements of the old philosophers, and the cycles and epicycles of ancient astronomy. We cannot in any case of causation assign the whole of the conditions, nor though we may reproduce them in practice, can we mentally distinguish them all, without knowing the essences of the things including them; and we therefore must not unconsciously ascribe that absolute certainty to axioms, which the ancient religionists did to creeds, nor allow the mind, which ever strives to insulate itself and its acquisitions, to forget the nature of the process by which it substituted scientific for common notions, and so with one as with the other lay the basis of self-deception by a pedantic and superstitious employment of them.
Doubt, the essential preliminary of all improvement and discovery, must accompany all the stages of man's onward progress. His intellectual life is a perpetual beginning, a preparation for a birth. The faculty of doubting and questioning, without which those of comparison and judgment would be useless, is itself a divine prerogative of the reason. Knowledge is always imperfect, or complete only in a prospectively boundless career, in which discovery multiplies doubt, and doubt leads on to new discovery. The boast of science is not so much its manifested results, as its admitted imperfection and capacity of unlimited progress. The true religious philosophy of an imperfect being is not a system of creed, but, as Socrates thought, an infinite search or approximation. Finality is but another name for bewilderment or defeat. Science gratifies the religious feeling without arresting it, and opens out the unfathomable mystery of the One Supreme into more explicit and manageable Forms, which express not indeed His Essence, which is wholly beyond our reach and higher than our faculties can climb, but His Will, and so feeds an endless enthusiasm by accumulating forever new objects of pursuit. We have long experienced that knowledge is profitable, we are beginning to find out that it is moral, and we shall at last discover it to be religious.
God and truth are inseparable; a knowledge of God is possession of the saving oracles of truth. In proportion as the thought and purpose of the individual are trained to conformity with the rule of right prescribed by Supreme Intelligence, so far is his happiness promoted, and the purpose of his existence fulfilled. In this way a new life arises in him; he is no longer isolated, but is a part of the eternal harmonies around him. His erring will is directed by the influence of a higher will, informing and moulding it in the path of his true happiness.
Man's power of apprehending outward truth is a qualified privilege; the mental like the physical inspiration passing through a diluted medium; and yet, even when truth, imparted, as it were, by intuition, has been specious, or at least imperfect, the intoxication of sudden discovery has ever claimed it as full, infallible, and divine. And while human weakness needed ever to recur to the pure and perfect source, the revelations once popularly accepted and valued assumed an independent substantiality, perpetuating not themselves only, but the whole mass of derivitive forms accidentally connected with them, and legalized in their names. The mists of error thickened under the shadows of prescription, until the free light again broke in upon the night of ages, redeeming the genuine treasure from the superstition which obstinately doted on its accessories.
Even to the Barbarian, Nature reveals a mighty power and a wondrous wisdom, and continually points to God. It is no wonder that men worshipped the several things of the world. The world of matter is a revelation of fear to the savage in Northern climes; he trembles at his deity throned in ice and snow. The lightning, the storm, the earthquake startle the rude man, and he sees the divine in the extraordinary.
The grand objects of Nature perpetually constrain men to think of their Author. The Alps are the great altar of Europe; the nocturnal sky has been to mankind the dome of a temple, starred all over with admonitions to reverence, trust, and love. The Scriptures for the human race are writ in earth and Heaven. No organ or miserere touches the heart like the sonorous swell of the sea or the ocean-wave's immeasurable laugh. Every year the old world puts on new bridal beauty, and celebrates its Whit-Sunday, when in the sweet Spring each bush and tree dons reverently its new glories. Autumn is a long All-Saints' day; and the harvest is Hallowmass to Mankind. Before the human race marched down from the slopes of the Himalayas to take possession of Asia, Chaldea, and Egypt, men marked each annual crisis, the solstices and the equinoxes, and celebrated religious festivals therein; and even then, and ever since, the material was and has been the element of communion between man and God.
Nature is full of religious lessons to a thoughtful man. He dissolves the matter of the Universe, leaving only its forces; he dissolves away the phenomena of human history, leaving only immortal spirit; he studies the law, the mode of action of these forces and this spirit, which make up the material and the human world, and cannot fail to be filled with reverence, with trust, with boundless love of the Infinite God, who devised these laws of matter and of mind, and thereby bears up this marvellous Universe of things and men. Science has its New Testament; and the beatitudes of Philosophy are profoundly touching. An undevout astronomer is mad. Familiarity with the grass and the trees teaches us deeper lessons of love and trust than we can glean from the writings of Fénélon and Augustine. The great Bible of God is ever open before mankind. The eternal flowers of Heaven seem to shed sweet influence on the perishable blossoms of the earth. The great sermon of Jesus was preached on a mountain, which preached to Him as He did to the people, and His figures of speech were first natural figures of fact.
